Thank you, Mr. Chair.
I have a few questions about materials.
First, what other materials could be dangerous? You talked about carbon 14, but I did not quite understand the logic behind that. Could you perhaps repeat what you said?
Second, you mentioned film, but there are other things. It could be anything. You talked about maps in particular. Could those things be reproduced before they are destroyed, so that the information is at least preserved?
Third, if the material is dangerous, who decides to destroy the object in question?
